What to Record When Laboratory Reagents Arrive
Give the arrival its own identity
A purchase order confirms what was requested; it does not establish what reached the laboratory. Create a receipt entry for the actual delivery and give it an internal identifier before individual containers become separated from their packaging. For UK teams receiving parcels through a central goods desk, record the handover as well as the courier delivery time.
Capture the supplier name, catalogue description, stated batch or lot, number of containers, labelled quantity and receiving staff member. Preserve the wording of unusual identifiers rather than silently standardising them. OECD guidance on test-item management treats receipt and identification as parts of a material’s lifecycle; its GLP context should be distinguished from local research practice.
Describe what was observed
Use direct observations: “outer carton wet at one corner; two labelled vials present; photographs R-014-a to c saved”. Avoid conclusions such as “material ruined” unless a competent assessment supports them. Record whether any transport monitor was present and where its original data were saved. An absent monitor is missing evidence, rather than evidence of a particular temperature.
A useful discrepancy note could read: “Order lists lot EP-A; container states EP-B; held pending supplier clarification, query Q-021.” This preserves the mismatch without inventing a transcription correction. Keep damaged packaging photographs linked to the receipt entry if relevant to the review.
Connect the supporting documents
List the certificate, safety data sheet and any product-specific handling information received, including their versions or dates. Check that documents refer to the delivered identity and batch where applicable. HSE explains the role of safety data sheets in informing workplace risk assessment. An SDS and an analytical certificate serve different purposes.
The certificate library can be a starting point for finding analytical paperwork. Save the document actually reviewed in the laboratory’s controlled location, with the retrieval date, so a future website update does not erase the context of the original decision.
Record the next authorised step
End the receipt entry with a status, storage-location reference and named decision owner. Useful statuses distinguish awaiting documentation, under review and available for a specified project. Moving a container into its designated location should not silently imply scientific approval.
Before closing the record, ask whether another researcher could identify the exact container, find its documents and understand any unresolved question. That practical reconstruction test is often more useful than adding another untargeted tick box.
